And now an infuriated Ronson has taken to her MySpace blog to hit out at the unnamed female attacker.

She writes: “I’m p**sed at the bag of flour thrown on Lindsay last night. Not because I got powdered down, but because the girl who threw it acted like an animal herself. I take that back, it’s an insult to animals to group her in with them – my dog is FAR more civilised than that person. I think there are plenty of families that could have used that flour for a meal. Nice job, lady.”

It’s believed the flour-thrower was connected to animal rights group People for the Ethical Treatment of Animals (PETA), which has blasted Lohan in recent days for wearing fur coats.
